can u wire up the just the wideband o2 sensor to the s300 ? i ask this cuz i have a wideband sensor laying in my garage and was wondering if it can b of some use.. i dont have the controler r gauge.. just the sensor.. thanks

i tried connecting the LC-1 up to the ELD on my JDM P72 & the thing seemed to be consistently 1 full AF point out across the normal working range of the engine(i cant remember whether it was up or down).And no,there was def no installation errors or voltage offsets present.

So i just rerouted the LC-1 to the D12 EGR input & it came up perfectly.

This may or may not help some others out,but can anyone point out a reason for the discrepancy on the ELD input?

My factory OBD2B A plug doesn't have a wire going into slot A30, so I am under the impression I have to insert a pin into A30 and connect the wideband analog wire to that?? Is there a link or blown up image I can check to see the exact location of R136 and R138 so I will have to cut them??

ok I did that, and I am still not getting a proper reading, so I am routing the analog ground wire from the AFX to where I originally had it routed to....the neg terminal of the battery which is also what the AFX instructions sais to do....last week my tuner told me to route the ground wire to any sensor ground at the ECU, and I think that might be where I am going wrong.....Most guys here use ELD as the wideband input and cut the R136 and R138 , and they all have good reading in the end so this is my last resort in trying to fix this....

All grounds should go to the same place. With a B-Series engine this is the thermostat housing - the ECU & wideband should both ground to this point. Using the battery negative terminal creates a corrent loop.
